Method and UE for determining request for resources from network apparatus in wireless network
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein relate to a method for determining request for resources from a network apparatus in a wireless network by a first UE of a multi-USIM UE. The method includes determining that the first UE of the multi-USIM UE need to request for resources from the network apparatus in the wireless network to transmit pending uplink data to the network apparatus or receive pending downlink data from the network apparatus.
1. A method performed by a user equipment (UE) supporting a multi-universal subscriber identity module (MUSIM) in a wireless network, the method comprising:
determining whether to release a connection associated with a first USIM of MUSIM for a second USIM of MUSIM;
determining to set a release request indication in a non-access stratum (NAS) message in case that the connection associated with the first USIM of the MUSIM is determined to release; and
transmitting, to a network apparatus, the NAS message with the release request indication,
wherein uplink data status information and allowed protocol data unit (PDU) session status information are not included in the NAS message, in case that the release request indication is set in the NAS message.
2. The method of claim 1 ,
wherein a follow-on request indicator is not included in the NAS message, in case that the release request indication is set in the NAS message.
3. The method of claim 1 , wherein active status information is not included in the NAS message, in case that the release request indication is set in the NAS message.
4. The method of claim 1 , further comprising:
determining an update of new paging restriction information is needed during the UE is being in an idle state or an inactive state,
wherein the UE waits to update the new paging restriction information until a new NAS procedure is triggered.
5. The method of claim 4 , further comprising:
determining whether the new NAS procedure is triggered due to a first reason different from a second reason for updating paging restriction information; and
transmitting a new NAS message including the new paging restriction information based on the new NAS procedure.
6. The method of claim 1 , further comprising:
in case that the UE wants to update paging restriction information, initiating a first NAS procedure with a follow-on request indicator being set follow-on request pending; and
not releasing a NAS signaling connection after a completion of the first NAS procedure; and
transmitting a new NAS message including the paging restriction information and the release request indication after the completion of the first NAS procedure.
7. A user equipment (UE) supporting multi-universal subscriber identity module (MUSIM) in a wireless network, the UE comprising:
a transceiver; and
a processor configured to:
determine whether to release a connection associated with a first USIM of MUSIM for a second USIM of MUSIM,
determine to set a release request indication in a non-access stratum (NAS) message in case that the connection associated with the first USIM of the MUSIM is determined to release, and
transmit, to a network apparatus via the transceiver, the NAS message with the release request indication,
wherein uplink data status information and allowed protocol data unit (PDU) session status information are not included in the NAS message, in case that the release request indication is set in the NAS message.
8. The UE of claim 7 ,
wherein a follow-on request indicator is not included in the NAS message, in case that the release request indication is set in the NAS message.
9. The UE of claim 7 , wherein active status information is not included in the NAS message, in case that the release request indication is set in the NAS message.
10. The UE of claim 7 , wherein the processor is further configured to:
determine an update of new paging restriction information is needed during the UE is being in an idle state or an inactive state,
wherein the UE waits to update the new paging restriction information until a new NAS procedure is triggered.
11. The UE of claim 10 , wherein the processor is further configured to:
determine whether the new NAS procedure is triggered due to a first reason different from a second reason for updating paging restriction information, and
transmit a new NAS message including the new paging restriction information based on the new NAS procedure.
12. The UE of claim 7 , wherein the processor is configured to:
in case that the UE wants to update paging restriction information, initiate a first NAS procedure with a follow-on request indicator being set follow-on request pending, and
not release a NAS signaling connection after a completion of the first NAS procedure, and
transmit a new NAS message including the paging restriction information and the release request indication after the completion of the first NAS procedure.
13. A method of a network apparatus in a wireless network, the method comprising:
receiving, from a user equipment (UE) supporting a multi-universal subscriber identity module (MUSIM), a non-access stratum (NAS) message including release request indication and new paging restriction information;
deleting an old paging restriction;
storing the new paging restriction information; and
applying the new paging restriction information based on the NAS message,
wherein uplink data status information and allowed protocol data unit (PDU) session status information are not included in the NAS message, in case that the release request indication is set in the NAS message.
14. The method of claim 13 ,
wherein a follow-on request indicator is not included in the NAS message, in case that the release request indication is set in the NAS message, and
wherein active status information is not included in the NAS message, in case that the release request indication is set in the NAS message.
15. The method of claim 13 ,
wherein the UE waits to update the new paging restriction information until a new NAS procedure is triggered, and
wherein, in case that the new NAS procedure is triggered due to a first reason different from a second reason for updating the new paging restriction information, the NAS message including the new paging restriction information is received from the UE.
16. The method of claim 13 ,
wherein, in case that the UE wants to update paging restriction information, a first NAS procedure is initiated with a follow-on request indicator being set follow-on request pending,
wherein a NAS signaling connection is not released after a completion of the first NAS procedure, and
wherein a new NAS message including the paging restriction information and the release request indication is received from the UE after the completion of the first NAS procedure.
17. A network apparatus in a wireless network, the network apparatus comprising:
a transceiver; and
a processor configured to
receive, via the transceiver from a user equipment (UE) supporting a multi-universal subscriber identity module (MUSIM), a non-access stratum (NAS) message including release request indication and new paging restriction information,
delete old paging restriction,
store the new paging restriction information, and
apply the new paging restriction information based on the NAS message,
wherein uplink data status information and allowed protocol data unit (PDU) session status information are not included in the NAS message, in case that the release request indication is set in the NAS message.
18. The network apparatus of claim 17 ,
wherein a follow-on request indicator is not included in the NAS message, in case that the release request indication is set in the NAS message, and
wherein active status information is not included in the NAS message, in case that the release request indication is set in the NAS message.
19. The network apparatus of claim 17 ,
wherein the UE waits to update the new paging restriction information until a new NAS procedure is triggered, and
wherein, in case that the new NAS procedure is triggered due to a first reason different from a second reason for updating the new paging restriction information, the NAS message including the new paging restriction information is received from the UE.
20. The network apparatus of claim 18 ,
wherein, in case that the UE wants to update paging restriction information, a first NAS procedure is initiated with a follow-on request indicator being set follow-on request pending,
wherein a NAS signaling connection is not released after a completion of the first NAS procedure, and
wherein a new NAS message including the paging restriction information and the release request indication is received from the UE after the completion of the first NAS procedure.
